Buying Guide: How to Choose Certificate of Authenticity

Understanding Certificates of Authenticity

A COA is only as valuable as the source behind it. In a market flooded with forgeries, understanding authentication separates smart collectors from scam victims.

The Authentication Hierarchy

Witnessed Signings (Highest)
Authentication company representative physically present during signing. PSA/DNA, JSA, Beckett offer this service. Maximum trust.

Expert Authentication
Signature examined against known exemplars by trained experts. PSA, JSA, Beckett provide this service. Strong but not infallible.

Dealer/Seller COAs
Paper from the seller claiming authenticity. Value depends entirely on seller reputation. Many are worthless or fraudulent.

No COA
Buyer beware. Unless you personally witnessed the signing, assume nothing.

### Major Authentication Companies

PSA (Professional Sports Authenticator)
Dominates sports cards; strong in autographs. DNA program well-regarded.

JSA (James Spence Authentication)
Autograph specialists. Strong in vintage and deceased celebrity signatures.

Beckett (BAS)
Strong in sports. Witness program growing. Grading and authentication both.

### COA Red Flags

Generic certificates without specific item details
- No reference numbers or database verification
- Unknown authentication companies
- Seller refuses third-party authentication
- Price too good for alleged authenticity
- Certificate printed at home (obvious)

### Preserving Documentation

Store Separately: If item damaged, documentation survives
Archive Quality: Acid-free sleeves and boxes
Digital Backup: Photograph certificates and receipts
Link to Items: Document which COA belongs to which item

### When to Re-Authenticate

Already have items with questionable COAs? Submit to major authentication companies. Cost: $30-100+. Either you confirm value or learn the truth. Knowledge beats uncertainty.

Frequently Asked Questions About Certificate of Authenticity

Is a COA proof that something is authentic?

Not automatically. COA value depends on source. Third-party authentication (PSA, JSA, Beckett) carries weight. Dealer-issued COAs vary wildly—some trustworthy, many worthless. A fake item can have a fake COA. Authentication from major companies is the only reliable proof.

Which authentication company is best?

PSA leads sports cards and is strong in autographs. JSA specializes in autographs with particular strength in vintage. Beckett is strong in sports. All three are respected. Choose based on your collecting area and check which commands highest premiums in your market.

Can I get items re-authenticated?

Yes. Submit to PSA, JSA, or Beckett for examination. Cost is $30-100+ depending on value and turnaround. They'll either authenticate (confirming value) or reject (providing closure). Worth doing for questionable items before selling.

How do I store COAs properly?

Archival sleeves prevent handling damage. Store in acid-free boxes away from light and humidity. Keep separate from items (if one damaged, other survives). Photograph everything for digital backup. Link certificates to specific items in your records.
